2. Ears

Mark Nixon, a biometric expert from University of Southampton said 99.6% of ear shapes are very unique and distinguish one person to others. Nixon also said age will not change someone’s ear (shape). In contrast to fingerprints which change after the injury, changes of your ear will only occur in auricle (slightly decrease along with aging), but shape remains the same.
